Abstract
The azimuthal direction of the mechanical anisotropy of a material is measured by using a first transducer to transmit shear acoustic energy through the material and a second transducer, cross-polarized with respect to the first transducer, to receive the shear acoustic energy after it has traveled through the material. Amplitude and phase of the cross-polarized shear acoustic energy are measured as a function of the azimuthal rotation of the shear acoustic energy transducers with respect to the material.
